Introduction
About me:> Kyle Rush
• Software Developer – Leidos• Saxton Transportation Operations Laboratory (STOL) –
Federal Highway AdministrationAbout the tool:
> U.S. DOT Funded & Developed Tool
> Creation of SAE J2735 MAP Messages via a web application
> Available for use by any interested parties
> Under current development and enhancement at the STOL
Overview
MAP Messages> Describe physical layout of an intersection or stretch of roadway
in a digital form• Lanes and stop bars• Crosswalks• Signal group assignments• Allowed maneuvers
> Lanes and other objects in message constructed as set of points connected by straight lines
> Used by connected vehicles for safety critical applications
> Standardized by SAE J2735
Overview
MAP Tool
> Provides a simple, web application UI to build MAP messages by drawing geometry on map tiles
> Allows for configuration of data fields with descriptions, units, and min/max values
> Able to generate actual binary output for broadcast at RSU
> Tool is available at: https://webapp.connectedvcs.com/
> Support is available at: https://cvcs.samanage.com

MAP Creation Summary
1. Create parent MAP
1. Reference point at center of intersection
2. Verified point at known accurate location
3. Configure intersection data (name, speed limit, etc.)
4. Save file to computer
1. Create child MAP1. Load parent MAP created
in 12. Draw vehicle lanes
connecting to intersection, from stop bar backwards
3. Group vehicle lanes into approaches
4. Draw crosswalks5. Fill in vehicle lane details6. Fill in approach details7. Fill in crosswalk details8. Configure “connects to”
values and signal groupings for all vehicle lanes
9. Save file to computer
Complex MAP ExampleNYC intersection of Tillary and Flatbush
MAP Encoding& MAP Validator
MAP Encoding Summary
2016 SAE StandardMessage Type
> ISD = Unified Signal Phase and Timing (SPaT) + MAP used by Safety Pilot Program
> MAP = Raw MAP message contents not suitable for broadcast
> MAP + Frame = Raw MAP message contents wrapped in message frame, broadcast ready, recommended setting
> SPaT = Raw SPaT message contents not suitable for broadcast
> SPaT + Frame = Raw SPaT message contents wrapped in message frame, broadcast readyNode Offsets
> Explicit = Double precision latitude/longitude coordinates at every point
> Standard = Single precision latitude/longitude coordinates at every point
> Compact = Uses smallest offset type that can be used for every point
> Tight = Optimizes offset size on a point by point basis, produces smallest message, recommended setting
